Environmental Engineering Program

Introduction

The graduate program in Environmental Engineering provides a core background in water chemistry, environmental biology, and process dynamics. Advanced course work in water and wastewater treatment, bioremediation, pollutants and risk, ground and surface water hydrology, and air pollution is available in Civil Engineering and other allied departments.

Environmental Engineering Research

Original research is a primary component of a graduate program. Current fundamental environmental research will serve as the basis for solving the problems faced by future generations. Practical engineering research is necessary to solve current environmental problems. The following are some of the research topics that Environmental Engineering students and faculty have explored in the last few years:

  • Airborne Transport of Pesticides
  • Biological Nutrient Removal
  • Bioremediation of Subsurface Contaminants
  • Fate of Endocrine Disrupting Chemicals in Wastewater Treatment
  • Grass Swales for Treatment of Roadway Runoff
  • Pathogen Fate and Treatment in Bioretention
  • Suspended Solids Capture and Accumulation in Bioretention
  • Dissolution of Nonaqueous Phase Contaminants

Environmental Engineering research is conducted in four very well equipped, air-conditioned laboratories totaling approximately 3000 square feet.

Course Requirements

For the Master of Science degree, three Core courses are required for all students:

  • ENCE 650 - Process Dynamics of Environmental Systems
  • ENCE 651 - Chemistry of Natural Waters
  • ENCE 637 - Biological Principles of Environmental Engineering

Additionally, three other courses should be selected from the list of environmental and water resources class below. The remaining 2 or 4 courses (depending on the degree option chosen, as described further below) are electives and must be approved by the student's advisor. More than three courses from the list below can be taken, with the extra used as electives. Course requirements for the Ph.D. degree are described below.
